About niobium triselenide
Niobium triselenide is a metallic transition-metal dichalcogenide that occupies a stable position on the thermodynamic convex hull. Its structural complexity is highlighted by a high number of reported phases, making it a subject of extensive investigation in materials science. The material is primarily utilized in fundamental research to explore collective electronic states and charge density wave phenomena. Due to its metallic nature, it serves as a key platform for studying low-dimensional electronic transport.
Key Properties
Cross-validated computational properties for niobium triselenide, aggregated across 5 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
